For Use With
|Landing Tile||S-726 Stair Tread & Landing||Roll tile with 100 lb. roller; install tile in same direction; dry fit all tile before bonding|
All substrates listed below must be properly prepared.
- Concrete (all grade levels)
- Wood Underlayments (1” minimum thickness)
- Polymeric Poured (seamless) Floors
- Ceramic Tile
Check tile for correct color, shade and amount.
Do not store tile outside or on the ground. Do not stack skids or other materials on Armstrong Tile.
Subfloors/underlayments shall be dry, clean and smooth. They shall be free from paint, varnish, solvents, wax, oil, existing adhesive residue* or other foreign matter. For more detailed requirements of concrete, wood and metal subfloors, as well as wood and trowelable underlayments, refer to the Armstrong Guaranteed Installation Systems manual, F-5061, Section IV., Subfloors and Underlayments.
Calcium Chloride Tests for moisture must be conducted. Armstrong offers a guideline of a maximum acceptable moisture emission level of 3.0 lbs. per 1000 sq. ft. per 24 hours. Bond Tests should also be conducted for compatibility with the substrate. When testing for alkalinity, the allowable readings for the installation of Armstrong flooring are 5 to 9 on the pH scale. Temperature shall be maintained at a minimum of 65° F (18° C) and a maximum of 85° F (29° C) for 48 hours prior to installation, during installation and 48 hours after completion. A minimum temperature of 55° F (13° C) shall be maintained thereafter. Condition all flooring materials and adhesives to room temperature at least 48 hours prior to starting installation. Protect all materials from the direct flow of heat from hot-air registers, radiators, or other heating fixtures and appliances.
When using S-726 Stair Tread & Landing Adhesive in remodeling, remove enough of the existing adhesive residue* so that at least 80% of the original substrate of the overall area is exposed.
Note: Some previously manufactured asphaltic “cutback” adhesives contained asbestos. For removal instructions, refer to the Resilient Floor Covering Institute’s publication Recommended Work Practices for Removal of Resilient Floor Coverings.
Installing Landing Tile is not recommended over slab expansion joints. Install the tile 1” to 3” from expansion joint on both sides. Cap this area with a plate that is fastened to the slab on one side only, allowing the plate to slide without restriction.
- Lighting conditions must be bright enough to observe color consistency, registration, thickness differences and jointing quality. Permanent lighting is essential.
- Line off entire area to be installed, refer to vct tile layout in Chapter 6, Layout and Fitting
- Keep border tile size ½ the tile size or more whenever possible. Fit tile tightly at walls to help prevent tile shifting and adhesive oozing during bonding.
- Apply Armstrong S-726 Stair Tread and Landing Adhesive using a 1/16″ x 1/16″ x 1/16“ V notch trowel.
- Allow 5-10 minutes open time on porous substrates and allow adhesive to dry to touch over non-porous substrates.
- After the adhesive is ready, place the first tile squarely into position at the point where the center lines cross. It is very important to lay the first few tiles perfectly on the guidelines as they will affect the entire installation.
- Do not pressure fit the tile joints. A very small amount of expansion may occur with use.
- Roll tile diagonally and slowly in both directions with a 100-lb. roller. Roll again in one hour.
- Roll any loose corners or edges of tile with the S-77 Hand roller. If necessary, reroll the entire installation with a 100-lb. roller.
- Continue installing the remaining tile following steps 9-16.
- Remove any uncured adhesive from the surface of the tile by gently rubbing the soiled area with a clean, white cloth dampened with neutral detergent and water.
- After 72 hours, wash the floor with a neutral detergent (pH of 7-8) to remove the mold release on the face of the tile. The mold release attracts dirt, causing excessive soiling until it is removed.
- Pedestrian traffic is not recommended for at least 24 hours after installation.
